Investigating the ice nucleation activity of organic aerosol
… by altering cloud properties. Aerosol-induced ice nucleation includes several processes that impact cloud formation, lifetime, albedo, and precipitation efficiency. Ice nucleating particles (INPs) promote ice formation at warmer temperatures and lower relative humidities than required to …

Genomic, transcriptomic, and metagenomic approaches for detecting fungal plant pathogens and investigating the molecular basis of fungal ice nucleation activity
… roles in the atmosphere because of their ice nucleation activity (INA). INA is the capacity of some particles to induce ice formation above the temperature that pure water freezes (-38°C). Importantly, INPs affect the ratio of ice crystals to liquid droplets in clouds, which in turn …

Effects of simulated acidic precipitation on the colonization and ice nucleation activity of Pseudomonas syringae pv. syringae and Erwinia herbicola
Precipitation over the eastern United States has been increasing in acidity, particularly within the last three decades. The average annual pH of rain in this area is about 4.2. The foliar surface, or phylloplane, of soybean can be damaged by rain acidified to pH 2.9. Simulated acidic precipitation …

Fluorescent Biological Aerosol Particles in Coastal Canada and the Link to Atmospheric Ice Nuclei
… and bacteria) have been shown to be effective ice nuclei (IN) and cloud condensation nuclei (CCN).</p> <p>During 21 days in August 2013 we participated in a collaborative international campaign at a rural, coastal site near the village of Ucluelet on the west coast of Vancouver Island, British …

Identification and characterization of ice nucleation active bacteria isolated from precipitation
… are capable of catalyzing the formation of ice at relatively warm temperatures utilizing a specific protein family which aids in the binding of water molecules. However, the overall biodiversity, concentration, and relationship of ice nucleation active (ice+) bacteria with air mass …

Water on Calcite (10.4) and K-Feldspar (001) - Adsorption Structure and Desorption Kinetics -
… weathering of rocks, and atmospheric ice nucleation by mineral dusts. These small-scale processes at mineral-water interfaces have tremendous impact on our environment. For instance, ice nucleation caused by mineral dusts changes the properties of clouds, and, thus, influences our …

Identification, Characterization, and Use of Precipitation-borne and Plant-associated Bacteria
… decaying vegetation as a source of atmospheric Ice Nucleation Particles (INPs), I analyzed a historic leaf litter sample collected in 1970 that had maintained Ice Nucleation Activity (INA) for 48 years. A culture-dependent analysis identified the bacterial species Pantoea ananatis and the fungal …
